NITED STATES PATENT OFFICE,

JOHN DIEHL, OF FRANKSVILLE, VISOONSIN.

SPECIFICATION forming part of Letters Patent No. 396,272, dated January15, 1889. Application filed August 24, 1888. Serial No. 283,653. (Nomodel.)

T0 all whom it may concern:

Be it known that I, JOHN DIEHL, of Franksville, in the county of Racine,and in the State of Visconsiinhave invented certain new and usefulImprovements in /Tehicle-Springs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to vehicle-springs, being designed as animprovement on the device set forth in Patent No. 379,763, dated March20, 1888, said invention consisting in certain peculiarities ofconstruction and combination of parts to be hereinafter described withreference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a side elevation of myimprovedvehicle-spring with parts broken away; Fig. 2, a plan view of the same;Fig. 3, an under side view of an adjustable socket and guide that issecured to each end of the spring-bar, and Fig. 4 a detail plan view ofa portion of my device.

Referring by letter to the drawings, A represents a bar having each endthereof provided with recesses B C, that are preferably extended throughsaid bar. Over the openings thus formed are bolted or otherwise suitablysecured metallic plates D; but it is obvious that the recesses B C mayonly extend part way through the bar A, and in such a case the plates Dwould be omitted. y

Bolted or otherwise suitably secured to the central portion of the barA, and preferably between the latter and a stay-plate, E, is asemi-elliptic spring, F, having upwardly and outwardly curved ends, F,recessed, as shown at G, to straddle the adjacent standards II of abolster, I, the latter being shown as provided with rub-irons I for saidends of spring' F. By havingthe ends of the semi-elliptic spring Fstraddlethe bolster-standards H there is no liability of said springbeing displaced from the bolster I by any jarring or wrenching of avehicle to which my device may be applied. Adjacent to the recesses Ginits ends the semi-elliptic spring F is provided with lugs J, andsurrounding these lugs are spiral springs K, that extend up into therecesses O in the ends of the bar A.

Arranged in the recesses B in the bar A are spiral springs L, havingtheir upper ends in the form of eyes L for rivets M, that pass throughthe metallic plates D and thereby suspend said springs.

Vertically depending from the stay-plate E, on each side of its center,is a short spiral spring, N, and these springs, on coming into play,bear upon a rub-iron, O.

Sockets P, provided with slots Q, are slipped onto the ends of the barA, said sockets being ad j ustably held in place by means of set-bolts Rpassing through said bar and slots. The under sides of the sockets P areprovided with recesses S, in order to obtain clearance for the spiralsprings K, and the outer ends of said sockets are provided with lugs T,that come on opposite sides of the bolster-standards H, to preventdisplacement of the bar A, said lugs having downwardly-projectingextensions T', designed to come upon the upwardly and outwardly curvedends F of the Asemi-elliptic spring F when the resistance of the latterand the spiral springs K, L, and N is overcome by a load. l/Vhen thelugs T come upon the ends F of the semi-elliptic spring F, a furtherelastic resistance is offered to the load, because by their peculiarshape said ends are springs in themselves, and the result of theoperation just described is an equalization of the strain upon the mainportion of said spring F.

By employing the adjustable sockets P the bar A is readily lengthened toaccommodate the same to the slight differences in width between thebolster-standards H that occur in vehicles of different makes; and bythe general construction and arrangement of parts above described itwill be seen that I provide a very simple and durable spring capable ofsupporting heavy loads and not liable to be wrenched or jolted out ofposition.

It is obvious that the spiral springs K, L, and N may be omitted, andthe sockets P employed in connection with a spring composed ofthe barand semi-elliptic spring above described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A vehiclespring comprising a bar, a semi-elliptic spring secured tothe central portion of the bar, and sockets adjustably se- IOO cured tothe ends of said bar and provided with lugs designed to come on oppositesides of bolster-standards, substantially as set forth.

2. A vehiclespring comprising a bar, a semi-elliptic spring recessed atits ends and secured to the central portion of the bar, and sockets adjustably secured to the ends of said bar and provided with lugs designedto come on opposite sides of bolster-standards, substantially as setforth.

3. A vehicle-spring. comprising a bar, a semi-elliptic spring secured tothe centra-l portion of the bar and having upwardly and outwardly curvedends, and lugs depending from said bar to come upon said ends of theseinielliptic spring, substantially as set forth.

4t. A Vehicle-spring comprising a bar, a semi-elliptic spring secured tothe central portion of the bar and having upwardly and out` wardlycurved ends, and sockets adjustably secured to the ends of said bar andprovided with lugs having downward extensions, substantially as setforth.

5. A vehicle spring comprising a bar, the semi-elliptic spring I1",secured to the bar to have its ends rest upon the vehicle-bolster, andthe springs L, arranged to depend 'frein the bar and be normally out ofcontact with said seinielliptic spring, substantially as set forth.

G. A Vehicle-spring comprising a bar, a single semi-elliptic springsecured to the central portion of the bar, and two spiral springs ofdifferent lengths arranged to depend from each endv of said bar, wherebyone of the spiral springs ineach pair is always in contact with theseini elliptic spring and the other normally out of contact therewith,substantially as set forth.

7. A vehicle-spring comprising a bar, a single semi-elliptic springsecured to the central portion thereof, two spiral springs of differentlengths arranged to depend from each end of the bar, and short spiralsprings depending `froin beneath said semi-elliptic spring, whereby oneof the spiral springs in each pair is always in contact with thesemi-elliptic spring and the other normally out of contact therewith,substantially as set forth.

S. A vehicle-spring comprising a bar provided at each end with therecesses B C, the se1ni-elliptic spring F, the spiral springs K,arranged in the recesses C of the bar and iinpinged against the ends ofsaid seinielliptie spring', the springs L, arranged in the recesses 13of said bar and having their upper ends provided with eyes L', theplates D, and the rivets M, connecting said eyes and plates,substantially as set forth.

9. A vehicle-spring comprising the bar A, adjustable sockets P, arrangedon the ends thereof and provided with lugs T, having extensions T, thesemi-elliptic spring F, having the upwardly and outwardly curved ends F,and the spiral springs K L, of different lengths, suspended from saidbar, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set iny hand,at. Oakwood, in the county of Milwaukee and State of Tisconsin, in thepresence of two witnesses.

JOHN DIEIIL.
